IMPROVEMENT IN SIDE-HILL PLOWS.

Specification forming part of Letters Patent No. 117,054, dated July 18,1871; antedated July 12, 1871.

To all whom it may concern:

Be it known that I, DANIEL C. DAY, of San Jose, county of Santa Clara,State of California., have invented an Improved Side-Hill Plow; and I dohereby declare the following description and accompanying drawing aresutlicient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovements without further invention or experiment.

My invention relates to improvements in that class of side-hill plows inwhich two plows facing in opposite directions are used, and in which thebeam can be revolved about a central point so as to stand in front ofeither, as desired. My improvement consists in a peculiar method orarrangement for securing' the beam in place after it has been turned tothe required position.

In order to explain-my invention so that others can understand itsconstruction and operation, reference is had to the accompanying drawingforming a part of this specification, in which- A and B represent twoplows standing` in opposite directions, their land-sides C being unitedso as to form one extended land-side. The upper ends of the standards Dare secured to a plate, E, which is parallel with the land-side. Myinvention consists of a band or loop, F, which is secured by a bolt, a,which passes irough the beam from side to side, immediately above theend ofthe plate E. This loop is made sufficiently long to leave a spacebetween the beam and cross- .ends both above and below,.so that when itstands in a vertical position its lower end will embrace the end oftheplate E and retain it in place. A rod, Q, is attached to the upper endof the loop and reaches back to a lever, H, which is bolted to the beamnear its rear end, within easy reach ofthe plowman. B y drawing` thislever back the loop is caused to turn on the blt aso as to stand at anangle and thus releasethe plate E, Apin, I, similar to a king-bolt, isalso connected to the lever by a rod or wire, b, and operates in a holewhich passes through the beam and into the plate E directly in frontofthe lever H. The same movement of the lever which carries the loop toan angle withdraws the pin I suiiciently to free it from the plate E, sothat the beam can then be revolved so as to face in the oppositedirection, when, by moving the lever toward the front end of the bea-m,the loop and pin will secure it in the same manner, as above described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination, with the revolving plate E, of the band F, rod Q, pinI, rod b, and lever H, connected and arranged to operate together,substantially as and for the purpose herein set forth.

In witness that the above-described invention is claimed by me I havehereunto set my hand and seal this 7 th day of May, A. D. 1870.
